I disagree 100%. Age or length of time being a Master Mason has nothing to do with putting on a quality degree. From what I've seen, it's the seasoned members who botch the degree work and/or chat it up on the sidelines, not the new Brothers. If I wasn't allowed to participate on the degree team after being raised, I'd pack my bags and find a different Lodge.
i wouldn't say "100%." i know plenty of young MMs that think they know the work when they don't, and plenty of 50 year pins that could lay down the best, most emphatic ritual.
the natural conclusion is that being a MM, young or old, is no indication of amount of ritual known.
